ALUMINUM TRISTEARATE
ALUMINUM TRISTEARATE
Aluminium tristearate is a hard, thermoplastic white powder prepared from Stearic Acid and Aluminium.
Aluminum tristearate forms gels with turpentine, Mineral spirits, and oils.
It has been used as a Drier, thickener, Emulsifier, and matting agent in paints and varnishes although excess amounts produce soft, noncohesive films.
Aluminum tristearate is also used to waterproof fabrics, ropes, Paper, Leather, Concrete, and Stucco.
It is used as an ingredient in photographic emulsions.
Aluminum Tristearate is also known as aluminium tristearate and is a salt of aluminum and stearic acid.
Aluminum Tristearate is used as a viscosity-increasing agent in non-aqueous cosmetic and pharmaceutical formulations.
ALUMINUM TRISTEARATE is a low ash, free flowing, and fine powder product primarily for the crayon and drawing pencil applications.
It is a tristearate formulation, but it has a high free fatty acid content which provides high solubility and low gelling properties for fuel oils and petroleum distillates.
ALUMINUM TRISTEARATE is suitable for use in food packaging applications in accordance with many FDA Code of Regulations.
Aluminium tristearate, also known as aluminum stearic acid or aluminum(iii) stearate, belongs to the class of organic compounds known as long-chain fatty acids.
These are fatty acids with an aliphatic tail that contains between 13 and 21 carbon atoms.
Aluminium tristearate is a weakly acidic compound (based on its pKa).
Aluminium tristearate is a potentially toxic compound.

TOXICITY
Aluminum soaps have different and widespread applications (1-4), aluminum stearates being among them especially important. Aluminum tristearate is useful in paints and enamels and in the flatting of varnishes. It also prevents bleeding and oil separation in putty. Aluminum distearate is the most commonly used grade of aluminum stearate. It is used as a thickener in paints, inks and greases; a water repellent for leather and rope; and a lubricant in plastics and rope. It is also used in cement production for waterproofing and air entrainment, and in hot-melt paper coating compounds. Because of its unusually heavy bodying properties, aluminum monostearate is used in the manufacture of paints, inks, greases, and waxes (3). In recent years (5), hydrophobic aluminum monostearate was tested as a low-solubility denitrification substrate for anaerobic bacteria and a source of aluminum for phosphate precipitation. Aluminum stearate has potential for use in a flow-through container for denitrification of oxidized effluent from home sewage systems. It was also referred that the preheated mixture of metal soaps, along with the costabilizer, delayed the fast blackening of the polymer, but mainly showed a reduction

Aluminum Stearate
Odor: characteristic
Use: Aluminum Stearate is commonly used as a paint and varnish dryer, waterproofing agent, defoaming agent, cement additive, in lubricants, cutting compounds, and in some food and pharmaceutical products.
Aluminium stearate is a fine, bulky, odourless and colourless powder forming a plastic mass when heated, having the properties both of organic and inorganic matter.
It embraces most of the characteristics of other metallic stearates and is regarded as the most important of these.
ALUMINIUM STEARATE is a soft, fine fluffy free flowing bulky powder having characteristic odor. It has mild antiseptic and astringent properties.
It imparts smoothness to creams. It is a normal Aluminium soap of Stearic Acid and finds users in many industries. It is water repellent by nature and insoluble in water.
There are multiple types of aluminum stearates, generally classified as aluminum mono-, di-, and tri-stearate. They vary in terms of physical properties such as melting point, free fatty acids, and particularly the gelling properties.
Oils with a low viscosity are best thickened by aluminum di- and tri-stearate, whilst very viscous oils from stiffer gel when combined with aluminum mono- or di-stearates.
All aluminum stearates are highly hydrophobic, and feature outstanding transparency and excellent adhesion to metal surfaces. Due to their water repellency, aluminum di- and tri-stearate are used as hydrophobic agents in the building industry.
The Stearate salts, including Lithium Stearate, Aluminum Distearate, Aluminum Stearate, Aluminum Tristearate, Ammonium Stearate, Calcium Stearate, Magnesium Stearate, Potassium Stearate, Sodium Stearate, and Zinc Stearate are fine, white powders with a slight fatty odor.
In cosmetics and personal care products, Stearate salts are used mainly in the formulation of makeup products such as eyeliner, eyeshadow, mascara, lipsticks, blushers, face powders and foundations.
They are also used in fragrances, deodorants, and hair and skin care products.
The Stearate salts are generally used for their lubricating properties. They also help to keep emulsions from separating into their oil and liquid components.
The Stearate salts increase the thickness of the lipid (oil) portion of cosmetics and personal care products and reduce the clear or transparent appearance of finished products.

GREASES, LUBRICATING OILS: ALUMINIUM STEARATE gives excellent properties of transparency, stringiness and water repellency. It acts as a high temperature resistant when added in lubricants. ALUMINIUM STEARATE is used by ONGC for defoaming properties.
DRY LUBRICATION: Useful as a lubricant in metals processing, such as wire drawing, producing brighter products.
PAINTS, VARNISHES AND LACQUERS: Adequate for improving pigments suspension, control of viscosity and gloss, water resistance and improving brushing and penetration. It finds very wide application in paint industries for preparation of enamels and lacquers where it acts as thickening agent or suspending agent. It reduces sagging and setting of pigment and works as varnish drier. It is used as an important ingredient for water proofing in tarpaulin & textile industries.
PRINTING INKS: The high gelling properties of ALUMINIUM STEARATE are useful for thickening and suspension improving
PLASTICS: It is used in as a lubricant in the production of Polyamides and Thermosetting plastics.
RUBBER: Used as dusting powders to prevent sticking of unvulcanised rubber sheet.
CONSTRUCTIONS: Recommended jointly with CALCIUM STEARATE for improving the water resistance of concrete and cements.
